Which is actually the most important part of my reason for trying this;
I need to clobber (perldoc -f unlink) symlinks (perldoc -f symlink) older than 11 minutes. Unfortunately, Perls find2perl only provides:

-atime N
True if last-access time of file matches N (measured in days) (see bel+ow).
-ctime N
True if last-changed time of file's inode matches N (measured in days,+ see below).
-mtime N
True if last-modified time of file matches N (measured in days, see be+low).
-newer FILE
True if last-modified time of file matches N.
# # # See below: # # #
1. * N is prefixed with a +: match values greater than N
2. * N is prefixed with a -: match values less than N
3. * N is not prefixed with either + or -: match only values equal t+o N

NOTE: (measured in days, see below), which is different than the find the system provides.
As the system' find provides minutes. While I'm sure it must be possible to feed the string some math to make it more granular, I'm not clever enough to figure out how. :(
